Unable to slice sprite in Sprite Editor; Failed to create texture because of invalid parameters

Hello Unity Community,

I'm hoping you can help me with a small problem I'm having with the Sprite Editor. I'm attempting to slice a sprite with the Sprite Editor, but when I click the 'Slice' button, Unity throws this error:

UnityException: Failed to create texture because of invalid parameters

I've checked all my sprite settings and I think they're okay. I did some research and found mention that there might be a maximum sprite size, but I can't find a definitive limit anywhere, so I don't think that's the problem.

In Windows explorer the sprite sheet reports as being 15840 x 720 pixels. Here is a screenshot that has my sprite settings on the left, my slicing settings, and the error being thrown at the bottom:



Any suggestions on how to resolve this would be greatly appreciated. Thanks so much for your help!

Well that is definitely a very large texture... try cutting your texture to size of 4096x4096 (if you want to keep it POT + use compression) and see if it works then...

 

It's a couple years old, but this post seems to have your answer.

Summary: limit is 8192 x 8192, or less depending on hardware.

 

Thanks for the replies! I'm having my artist provide another version of the spreadsheet with multiple rows so that it will fit within those dimensions. I'll post again once I've tried with the new sprite sheet.

 

I got an updated sprite sheet from my artist today which had the sprites laid out in two rows instead of one and I was able to slice it with the Sprite Editor. Updated dimensions were 9360 x 1440. Still very large and the same area, but not tremendously long as the first one was. Hopefully this helps someone else in the future.
